Rolls Out Most Advanced Material for Stronger, More Fuel-Efficient Truck Wheels

CLEVELAND & ORLANDO, Fla.--Alcoa (NYSE:AA), the inventor and global leader of forged aluminum
wheels, today rolled out the most advanced aluminum wheel alloy in 45
years. The new material opens the door for lighter weight wheels at
increased strength with the same corrosion-resistant characteristics as
the industry standard, also made by Alcoa. Alcoa expects to introduce a
new, state-of-the-art wheel featuring the alloy in early 2014.

Unveiled at the American Trucking Association Management Conference &
Exhibition in Orlando, Florida, the new lightweight alloy, called
MagnaForce™, is on average 16.5 percent stronger than the industry
standard, Alcoa’s 6061 alloy, in similar applications. Alcoa will use
the material to manufacture wheels for commercial transportation, where
lighter weight products that increase fuel efficiency are in high demand.

“Alcoa is making truck wheel history with our innovative aluminum
material,” said Tim Myers, President, Alcoa Wheel and Transportation
Products. “No manufacturer has produced a wheel with an alloy superior
to Alcoa’s 6061 material. Our MagnaForce alloy today opens the door to
production of the strongest, lightest wheels to increase fleet payload,
improve fuel efficiency and enhance sustainability.”

Alcoa has been the industry leader since inventing the forged aluminum
wheel in 1948 using an alloy it had developed for the aerospace
industry. In 1968, Alcoa set the industry standard again when it
launched its 6061 alloy for forged aluminum wheels. Alcoa’s 6061
material provided a strong, durable alloy, resistant to corrosion that
is used to this day by all major forged aluminum wheel manufacturers.
During that time, Alcoa’s experts have continually met increasing
demands for lighter weight wheels, engineering products that today are
10 pounds lighter than wheels from 20 years ago, using the same alloy.

Alcoa’s scientists and engineers at the Alcoa Technical Center, the
world’s largest light metals R&D center located outside Pittsburgh,
invented the MagnaForce alloy following two years of development.

Alcoa Wheel and Transportation Products is part of Alcoa’s downstream
business, Engineered Products and Solutions. Through the third quarter
of 2013, Engineered Products and Solutions contributed 25% of the
company’s total revenues.
